It will lie-realized that, whereas I. have shown a practical and operative device, many changes may be madein the size, shape, number, and disposition of parts, and that I do not. wish to be limited specifically t0 the mechanisms described and s Iowa.

The use and operatlon of my invention I provide a valve J which normally closes the flue G and forces the flue gases to bypass throiigh thev passage G and thus through the center of the tank H. The gases are thus utilized to heat the domestic water supply which circulates through the heatand storage tank H. When the water in the tank reaches a predetermined maximum the element J transmits this temperature to the member J which, in turn, in response to its increase in temperature, moves, and there-' by moves the valve J and increases the opening of the passage G. I, The flue gases in mcreaslng volume take their normal assage through G instead of'G until a rop 1n the temperature of the tank H is reflected by a return of the valve J to partially or completely closed position. Obviously I may v if I desire, employ elements having a graduated effect. In this wise the valve J may be entirely closed or entirely open or may occupy intermediate positions, the supply of flue gases bein thus either entirely cut off or controlled rom a minimum to a maximum;

I claim: 1. In association with a'domestic heating plant, a domestic hot water supply tank, a

chimney passage for said heating plant, a bypass therefrom adapted to heat said tank, and thermostatic means for regulating the thermostatic member havpassage of flue gases throughv said bypass ng into, in response to the temperature of the water (1 transin said tank.

2. In association with a domestic heating therebetween responsive to changes in the temperature of said thermostatic element.

3.'In association with a domestic heating plant, a domestic hot Water supply tank, a chimney passage 'for said heating lant, a

.bypass therefrom adapted to heat said tank,

and thermostatic means for regulating the passage of fiue gases through said bypass in response to the temperature of the water in said tank, comprising in part a valve in;

the flue passage, a thermostatic element as-' lever and a thermostatlcally actuated lever and a connection therebetween;
